loaded ones immerses deeper so Fb is less when the rocks are taken out so the volume would be less...?? thus the water level will decrease??

my reasoning is because of the forces acting on it...the Fb=density of the fluid * gravity * volume and by taking the rock out, were increasing the Fb so increasing the volume?

I have been pondering about this for awhile now. If there are rocks on a boat (that's floating in a water) and one by one the rock is thrown onto the water. Does the water level rise or fall from the initial level? I believe that it will rise but am not 100% sure.

A cable lifts a 1260-kg elevator at a constant velocity for a distance of 42.3 m. What is the work done by (a) the tension in the cable and (b) the elevator's weight? For part a.) w=(Fcos(theta))s w=(fcos(0))s =fs and s= 42.3 part b.) Fcos(theta))s w=(fcos(180)s =-fs and s= 42.3 BUt...

Two cars are traveling at the same speed of 28 m/s on a curve that has a radius of 124 m. Car A has a mass of 1080 kg, and car B has a mass of 1500 kg. Find (a) the magnitude of the centripetal acceleration and (b) the magnitude of the centripetal force for Car A, (c) the magnitude of the...

So would it be .006584*60=.39504??

I'm not sure on how to go from period to RPM

A centrifuge is a device in which a small container of material is rotated at a high speed on a circular path. Such a device is used in medical laboratories, for instance, to cause the more dense red blood cells to settle through the less dense blood serum and collect at the bottom of the...

I thought about doing it this way 2.36=[2(32)-(x*9.8)]/x but not sure if this is correct or how to solve for x.

Is the tensthe tension is the 32.0N-mg mg=a so i plugged in 2.36 so 32-2.36=29.64 which is wrong...

A fisherman is fishing from a bridge and is using a "32.0-N test line." In other words, the line will sustain a maximum force of 32.0 N without breaking. What is the weight of the heaviest fish that can be pulled up vertically, when the line is reeled in with an acceleration whose magnitude is...

A toboggan slides down a hill and has a constant velocity. The angle of the hill is 8.80 with respect to the horizontal. What is the coefficient of kinetic frction between the surcae of the hill and the toboggan? So i used the formula: sum of forces(x)= cos (8.80)=0.98823 Forces (y)=...

So i did what you said and (55+38.8)9.8 and got 919.24 but it was wrong so I'm assuming that box 3 would create upward tension?? since it is hanging??

Box 1 is resting on the table with box 2 resting on top of box 1. a massless rope passes over a massless, frictionless pulley. One end of the rope is connected to box and the other end is connected to box 3. The weights of the three boxes are w1=55.0N, W2=25.7N. Determine the mangitude of the...

THANK YOU! so I solved it 0=5.52 *10^4-x x=55200 then for part b. The bouyance force is the force that goes up...would be considered same as normal force? and the answer is the same as the mass * g??
